Aerodactyl can be found in "Catch 10 Pokemon" research tasks at PokeStops located in and around the event area. Relicanth can be found in "Send 2 Gifts" research tasks.
Relicanth has been made available outside of New Zealand before as part of the Safari Zone Porto Alegre event in South America.
PvP Side Event
It also appears there is a Pokemon GO PvP mini-event happening at the convention as well.
Pokemon fansite Serebii posted the above picture which alludes to an event happening around the convention center but details are sparse. Check back to this post for full details on this officially sanctioned PvP event.
